A box has the shape of a rectangle or prism with height 28 cm. If the height is increased by 0.3 cm, by how much does the surface area of the box increase?

Answer:
4.5cm
Step-by-step explanation:
28cm+0.3cm=28.3cm
surface area=28.3cm×15cm=424.5cm
original surface area=28cm×15cm=420cm
different=424.5cm-420cm=4.5cm
